Aspirin desensitization following endoscopic sinus surgery is effective in patients with nonsteroidal antiinflammatory drug exacerbated respiratory disease.

ABSTRACT

INTRODUCTION: Aspirin desensitization (AD) is effective in relieving asthma and sinonasal outcomes in patients with non-steroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (N-ERD). So far, only a limited number of studies evaluated the effect of AD prospectively in a controlled manner in N-ERD. It is also a current approach to recommend endoscopic sinus surgery (ESS) before AD. This study aimed to prospectively document the clinical effects of AD for 1 year in patients with N-ERD who underwent ESS in the presence of a control group. METHODS: The study included patients with N-ERD who underwent AD (group 1, n = 22) and patients with N-ERD in whom desensitization was indicated but was not performed (group 2, n = 21). All patients had ESS before enrollment in the study. Asthma and rhinosinusitis outcomes were assessed at baseline and after 1 year. RESULTS: The study included a total of 43 subjects (F/M28/15, mean age 44.7 ± 2.8 years). Fewer patients had nasal polyp recurrency in group 1 (5/22, 22.7%) than in group 2 (11/21, 52.3%) at the end of the first year (p = 0.035). Smell-test scores were preserved only in group 1 after 1 year. There were significant decreases in the use of both asthma and nasal medications only in group 1. CONCLUSION: Our results strongly support the use of AD for the improvement of both nasal and asthmatic outcomes in patients with N-ERD for 1 year. We also recommend patients undergo ESS before AD. Further controlled studies are necessary to evaluate whether this effect lasts longer.
